The distance formula is d = (x^2 + y^2)^(1/2) This is the same equation used for both. In other words, the equation of a circle gives the radius of the circle in terms of x and y, while the distance formula gives the distance from the origin to the final point in terms of x a

Answer:
Step-by-step explanation:
Find h when v = 20 and r = 3
Putting values in the formula
20 = (3.14)(3)2h
20 = (3.14)(9)h
20 = 28.26h
20/28.26 = h
R when v = 100 and h = 5
100 = (3.14)r2(5)
100/5 = 3.14r2
20 = 3.14r2
20/3.14 = r2
6.36 = r2
Square root on both sides
2.52 = r
